I am an only child. I was raised with cousins who were similar to my age so it was kind of like I had siblings but not the same. I wanted to know how a sibling affects the way a child acts and if this affects them in certain areas in their life.
The article I found tells about some studies they did in china regarding only children. In china there used to be an only child policy in order to control the population. They conducted a study on university students who were an only child. They scanned their brains while also testing their personality, creativity, and intelligence. The tests showed that only children outperformed those with siblings on creativity, but consistently scored lower on agreeable personality traits. The scans demonstrated that the parts of the brain associated with the development of these were indeed structurally different in the two.The only children who performed higher on creativity showed a higher volume of gray matter in the parietal lobe, a part of the brain associated with mental flexibility and imagination. The scans of those only children who showed less agreeable traits showed less gray matter in the medial prefrontal cortex, a part of the brain known to be involved in thinking about the self in relation to others.
The researchers claim this shows that different family environments do affect children’s structural brain development, and the kind of upbringing we have shapes the kind of people we become on a neurological basis. They point out that other studies have already shown that only children tend to exhibit more positive developmental outcomes, such as higher intelligence and creativity, often demonstrated in achievements at school. However, the sole attention of parents, can result in personality traits such as dependency, selfishness, and social ineptitude. Only children miss out on early opportunities to develop and practice social skills, emotional support, and empathy.
